Activity Introduction

cc-secondary9-heroQuick summary: During this lesson students collect data on the trees in their schoolyard. They compare results and discuss possible reasons for different results taken from the same population. They take their learning outside and collect authentic data that they can draw real conclusions from.

This lesson is designed to be taught outside. It contains all the tools required for students to reap the benefits of being outdoors while learning the outcomes of the Australian Curriculum. By spending time outdoors and connecting to nature, students are more likely to care for and conserve nature as adults.

Thought starter: What if all the trees in the world were small?

Reflection

When different people collect data there is often differences in their results: Why do you think the class results were different?

Do you think the process of collecting data you used in this lesson is a useful way of collecting data about the environment? Why or why not?

What was the most frequently observed tree size?

Trees form an important part of our environment. They provide us with shade in the schoolyard but they are also home to many creatures. How can you use the information you gathered the help increase the number of trees around your schoolyard?
